Princess Elizabeth may have worn the tiara at private royal events, but she’s never been publicly pictured wearing it.
According to an expert, the reason why the Queen has never worn the Cartier Halo Tiara is unconfirmed, but there are several theories.
Kate Beavis, owner of the contemporary wedding blog Magpie Wedding, told Express.co.uk: “The Cartier Halo Tiara was made in 1936 for the Queen Mother but when handed down it was not worn by our Queen – some say because it wasn’t grand enough, and others that it was felt to be too showy when she received it during the war for her 18th birthday in 1944.
“However, her sister, Princess Margaret wore it a few times.”
